President Barack Obama and first lady Michelle Obama have made a new addition to the White House -- a Portuguese water dog named Sunny, who will join a long list of presidential pets who have attained a sort of celebrity status.

Sunny, born in Michigan in June 2012, arrived at the White House on Monday, and the first family picked out the name because they believed it fit her cheerful personality, according to a White House blog. The Obamas have a history of allergies in the family, and they zeroed in on a Portuguese water dog because they don’t shed.

Sunny is expected to be a companion and a “little sister” for Bo -- also a Portuguese water dog -- gifted by President Obama to his daughters for excusing his absence while he spent time away from home campaigning in the 2008 presidential race.

Since then, Bo has been pictured with the first family as they go about their official duties, "from visiting Walter Reed and the Children’s National Medical Center, to inspecting the Holiday decorations at the White House, to greeting guests at the White House on tours and during the Easter Egg Roll,” the White House blog read.

But, in October, the first lady hinted that Bo might be feeling a bit lonely as he “doesn't have enough dog interaction,” prompting her to organize a “doggie play date.” This might have influenced the Obamas' decision to get another pet.

“We suspect Sunny will follow in Bo's footsteps and keep the President company in the Oval Office, go for walks with the First Family after their 6:30 family dinner and even jump up on the First Lady’s lap from time to time!” the blog read, adding that the Obamas are making a donation to the Washington Humane Society in honor of Sunny.
